Abstract :
This paper evaluates the implementation of a Round-Trip-of-Flight (RToF) technique into a UHF transponder. Different possible transponder architectures are investigated and measurement results for a passive design are shown at circuit level. The chip is designed based on a 0.13 μm CMOS technology.
